From zero to a supervised agent in a few commands. This assumes you already have the binary — if not, see Install.

1. Start the server#

nullhub

This starts the server and opens your browser at the dashboard. NullHub tries a chain of local addresses, in order:

  1. http://nullhub.local:19800 — published via dns-sd/Bonjour or avahi-publish when available
  2. http://nullhub.localhost:19800
  3. http://127.0.0.1:19800

If you want the server without the browser popping open, or on a different address:

nullhub serve --host 127.0.0.1 --port 19800 --no-open

serve also accepts repeated --allowed-origin ORIGIN flags to authorize extra CORS origins (a Tailscale domain, for instance). The same list can come from the NULLHUB_ALLOWED_ORIGINS environment variable, comma-separated.

2. Install a component#

The kitchen is open; time to hire the chef. The terminal wizard walks you through provider, ports, and keys — the web UI's Install Component flow is the same wizard with the same steps:

nullhub install nullclaw

NullHub can install and manage four components: NullClaw, NullBoiler, NullTickets, and NullWatch. Details in Installing components.

3. Run it and look at it#

# start everything that's installed
nullhub start-all

# table of all instances, or one instance in detail
nullhub status
nullhub status nullclaw/main

# follow logs live
nullhub logs nullclaw/main -f

Instances are addressed as {component}/{instance-name} everywhere in the CLI and the API.

4. Check the dashboard#

Open the dashboard and you get status cards with periodic health checks, per-instance config editors, live log streaming over SSE, and the component UIs (workflow editor, store browser, Flight Recorder). Tour in Web dashboard.

What just happened#

  • The component's binary was downloaded (or built) according to its published nullhub-manifest.json — see Manifests.
  • Its config, binary, and logs landed under ~/.nullhub/.
  • The supervisor now restarts it on crashes, with backoff, and polls its health endpoint.
